The exercises that we need to do together, we're now going to play through in the key of E. I'm going to show you some ways of playing around the key of E, laying the thumb in different positions. While we're in this key of E, soemtimes I cover the A and the D strings with just one finger. Now, I do that all of the time, and it's about saving energy. However, most people don't do that, so I'll try to be aware so that you don't get confused.
